Before donating blood, you generally need to pay attention to the following aspects:
Before donating blood, you should get enough sleep and avoid staying up late.
Fasting should be avoided before donating blood to prevent hypoglycemia at the time of donation. Maintain a light diet and avoid spicy foods such as chili peppers, greasy and irritating foods such as barbecue and fatty meats, and high-protein foods such as seafood.
Medications, especially antiplatelet forming drugs, should be avoided before donating blood.
If you have pathogens such as hepatitis B virus, treponema pallidum, and HIV, do not donate blood. In addition, patients with bleeding tendencies and coagulation dysfunction cannot donate blood, such as leukemia, hemophilia, etc.
When donating blood, you should bring your valid identity documents, such as ID card, passport, driver's license, military ID card, etc.
Strenuous activities should be avoided after donating blood to avoid adverse reactions such as dizziness.
After donating blood, the puncture hole should be protected from infection, and it is best not to remove the band-aid on the puncture hole for 12 hours, and the needle should not be wet for 1 2 days.
After donating blood, you should supplement nutrients such as fresh lean meat and fruits rich in vitamin C to ensure adequate rest and promote rapid recovery.
After donating blood, a band-aid should be applied to cover the puncture hole, and 3 fingers should be used to press the needle hole along the vein for 5-10 minutes. Check the puncture hole for oozing or bleeding, and if there is bleeding, elevate the arm and continue to compress the area.
In general, there are still many precautions before and after blood donation, which must be strictly followed to avoid unnecessary harm to the body.
